Development with Xamarin or IntelliJ

[Egbert Jansen]

Hi,

We are at the beginning of an Android application development which will measure some patient data and store this data locally.

Eventually the data must also be stored using CommCare.

And now maybe a stupid beginners question:

Is there a reason why we should use Xamarin or IntelliJ for the Android development (in relation with the CommCare communication) or will both work fine?

Thanks in advance....

If you start a new project from scratch, the common way now is to use Android studio which is "just" IntelliJ + Android related plugins and tools.

 

https://developer.android.com/sdk/index.html

 

If you base your own software on the CommCareODK code itself, I suggest you suggest to the older, Eclipse based Android SDK as Dimagi's build documentation and files are based on Eclipse + ADT :

What are you trying to achieve ?

The application will be created from scratch and not based on the CommCareODK.

The user can input some patient data, questions and the app will measure some data (communication with hardware).

This will be with no internet connection.

When connected to the internet, data must be stored in the CommCare database. (this is a request for the future)

We already have a lot of experience with C#, so maybe Xamarin can be a good choice of creating Android apps.

But if IntelliJ or Android studio is a better way to go, we would like to hear that!

Thanks and best regards,

Egbert

If you have good C# experience then Xamarin may get you up and running faster. I've never looked at it before so can't give any info about how good it is or if you'll have trouble communicating with hardware etc. One potential problem is that you may end up tied to the Xamarin platform and if you do face any difficulties down the line you may not be able to 'port' your code to a normal Android dev environment.

On a slightly different topic, since you are thinking about integrating with CommCare there are two approaches:

1. Build a custom app that submits the data directly to CommCare HQ.

2. Build a custom app that the CommCare mobile client calls to get the additional data you need.

Using the second approach you would install both CommCare and your app on the phone and then CommCare would 'call out' to your app from a form to get any additional data you require. This option has the advantage of allowing you to focus on the data measurement and letting CommCare deal with authentication, submitting data, form design etc. This second approach is outlined here: https://help.commcarehq.org/display/commcarepublic/Integrating+External+Applications+with+CommCareODK

Depending on your workflow / project, writing an entire application is maybe not required. Maybe you could write just the hardware-reading bit as an Intent and call this Intent from CommCare ? That way you'll save yourself the hassle to write a data entry / question application as CommCare already does this pretty well ?

 

Here is the doc for Android Intent integration on the CommCare Wiki:

Just food for thoughts…

Ah, email collision, Simon… Seems like my message has been lost in the limbo for a while, sorry about that.
